Many people swear that wearing a "lakhovsky coil" cures arthritis. This is nothing more than a belt made of copper wire (the thicker the copper wire is the better) worn around the waist, so a DIY-job should be relatively simple. Apparently Mr. lakhovsky provided a considerable amount of hard evidence that copper's effects are beneficial to all life, showing that tumors in plants would just wither and die in a relatively short time. No side effects either so nothing to lose. Google for more info.
